Unsymmetric Tetraorganotin Compounds Containing Functionally Substituted Acetylenes

The functionally substituted acetylenic groups linked to tin may contain various heteratoms. These include oxygen, sulfur, nitrogen, phosphorous, tin and silicon or combinations of these elements. One compound vith a cyano group is included. The derivatives summarized in Table 108 are prepared by methods from the following scheme. Additional tetraorganotin compounds with acetylenic unsaturation may be found in Subchapters 2.7 1 1 1 2.7- 1 3
